To Measure Section A:

1. Take the length of Section A & multiply by the depth of Section A
   
   72" x 30" = 2160 sq. in.
2. Divide this number by 144
   
   2160 ÷ 144 = 15.0 sq. ft.

To Measure Section B:

1. Take the length of Section B & multiply by the depth of Section B
   
   54" x 30" = 1620 sq. in.
   
2. Divide this number by 144
   
   1620÷ 144 = 11.25 sq. ft.
   
   
3. Add the total of Section A & Section B & round to the nearest ¼ sq. ft.
   
   15.0 + 11.25 = 26.25 sq. ft.
   
   The total counter top is 26 ¼" sq. ft.
